“When did you last cry laughing because of me — actual tears?”

The question sits across the top; you each answer on your own page. Whoever writes second reads the first answer before writing — agree, argue, or correct the record.

Why this question

Recent history only. Set the scene properly.

And once you’ve both answered

What does it say that we can still do this to each other?

Answering it honestly

Whoever writes second reads the first answer before writing — properly, not a skim. Your page can agree, argue, or correct the record.
Be specific. Dates, places, what was playing, who else was there. Wrong details are welcome; they're evidence.
Don't negotiate a joint version. Two accounts that refuse to match are worth more than one polished one.

And the house rule, whatever the mode: leave a blank rather than write a lie. A blank can be filled later; a lie sits in the archive forever, and you both have to live with the paperwork.
